April 2026 monthly summary focusing on key accomplishments across bitmovin-player-ui and bitmovin-player-react-native. The month delivered user-visible improvements in captions accessibility, playback UX, and cross-platform stability, along with substantial UX and data model refinements to track selection and UI updates. Key features delivered: - CEA captions font sizing and safe-area improvements: minimum font size ratio, flooring for small/medium players, and ensuring captions render within the 80% safe area. - CEA captions offset rendering and transition fixes: captions no longer render behind player offset; end-of-session handling corrected; transitions no longer hang when captions aren’t pushed to the control bar. - Track ordering and comparator architecture improvements: added comparator functions for audio/subtitle ordering; moved comparators to track list items; improved handling when audio is temporarily unavailable; safer, more predictable reordering with a simple type alias; backward-compatible when comparator is not specified. - UI stability and developer experience enhancements: added ListSelector.onItemsChanged signal; improved usage/docs; exported additional types; clarified entry/reorder flows; improved config propagation. - Small-player and safe-area handling enhancements: safe-area applied only to small player sizes to avoid layout regressions; CEA small player fix entry added for UX on small devices. - Documentation, tests and quality improvements: changelog wording updates for CEA changes; container ownership tests; test isolation improvements for spies; RTL alignment for VTT cues; consistent comparator and UI update behaviors. Major bugs fixed: - CEA session cache bug: prevented reset when CEA was not enabled. - Multiple caption rendering/transition issues: fixed behind-offset rendering, end-of-session transitions, and push-up behavior; prevented hangs. - VTT subtitling and UI rendering: RTL alignment fixes; WebVTT background color now matches window color; VTT cue updates moved between subtitle containers correctly. - List/ordering robustness: corrected early returns in comparators, ensured list rebuilds on comparator changes, and stabilized overall ordering across different comparator functions. - Build/system hygiene: Kotlin version alignment, SafeArea integration, Expo/doctor dependency updates to improve CI reliability. Overall impact and accomplishments: - Improved accessibility and legibility of captions across devices, enhancing compliance and user experience; reduced UI edge-case defects related to captions, subtitles, and track ordering; delivered cross-platform improvements to React Native integration and developer experience; strengthened CI stability with build-system upgrades.
